WHY IT NEEDS A POLICY

Why send_test_email needs a policy

The tool sends an email, which is a create/write action (email record creation and delivery). It does not charge money (not Financial), does not irreversibly delete data (not Destructive), and does not execute arbitrary code (not Execute). The scope is limited to testing an email template to a single specified address, and any effects (test email delivery) are reversible or benign.

From the tool's definition send_test_email sends a test email to a specified address using an email template. This action creates/modifies email records and triggers email delivery.
